16. Biosynthetic and synthetic studies of the fungal metabolite galiellalactone
Sammanfattning : Galiellalactone is a fungal metabolite found in the basidiomycetes Galiella rufa and the unidentified strain A111-95. It has been shown to possess promising activities as an inhibitor of the IL-6 mediated STAT3 signaling in HepG2 cells. LÄS MER
17. Synthesis of organobromines as a tool for their characterisation and environmental occurrence assessment
Sammanfattning : Polybrominated diphenyl ethers (PBDEs) have been intensively used as flame retardants (FRs) and have become ubiquitous environmental pollutants. PBDEs form hydroxylated PBDEs (OH-PBDEs) as metabolites. Further, some OH-PBDEs and methoxy-PBDEs (MeO-PBDEs) are natural products. LÄS MER
18. Synthesis of Novel Polyhydroxyl Surfactants. Influence of the Relative Stereochemistry on Surfactant Properties
Sammanfattning : This thesis deals with the synthesis and characterization ofnovel polyhydroxyl surfactants. The first part describes thesynthesis of a number of stereoisomers of a polyhydroxylsurfactant, and the second part concerns surface chemicalcharacterization. LÄS MER
19. An Organic Chemistry Odyssey : Imaging Mass Spectrometry in Neurotherapeutics, Asymmetric Methodology Development and Natural Product Synthesis
Sammanfattning : The development of imaging technologies and brain models is crucial for advancements in neurotherapeutic drug discovery and development. They assume a critical role in evaluating essential parameters such as drug blood-brain barrier (BBB) permeation, distribution, and metabolism, all of which are vital for the development of safe and effective medications.
